我有一个像

这样的字符串

https:\/\/scontent.xx.fbcdn.net\/hphotos-xta1\/v\/t1.0-9\/p50x50\/11139440_1010664825611559_1305796970308877058_n.jpg?oh=6da07776dd8ba8270c2c32de2957b7d3&oe=560D0AF0

我想用preg_replace函数替换所有“\” 就像这样

https://scontent.xx.fbcdn.net/hphotos-xta1/v/t1.0-9/p50x50/11139440_1010664825611559_1305796970308877058_n.jpg?oh=6da07776dd8ba8270c2c32de2957b7d3&oe=560D0AF0

示例：

• https： // - ＆gt; HTTPS：的 //
• net / hphotos-xta1 / - ＆gt;净/ hphotos-xta1 /

我如何实现这一目标？
